John:
I added a print statement before and after the first i2c write and it is definitely the I2C that is hanging up, it doesn't get through the write statements. Great call!
Now I have to figure out if that chip also died, or if there is another issue. I've got to leave for a while, so I probably won't look at it again until tonight.

Hello Howard,

Based on what you describe I suspect an issue with the I2C bus.

Suggested tests would be either to
a) Comment out the wire.xxxx call lines in the si5351 tab or
b) Load my test program (in the file section) as it performs 3 gradual tests of the bus, including writing to the si5351 but with a timeout. So it will always return a result, positive or negative.

From memory the wire library uses blocking call for sending data over the bus. So if the communication is not possible it would hang there.

Reasons could be defective nano A4/A5, short/open circuit in bus lines, defective si5351.

John:
I did find a short between D3-D4-D5 under the connector to the uBitx main board. I don't know how that happened, since I didn't touch that connector doing the rework. Anyway, the problem didn't go away after clearing the shorts. I loaded your ubitx_diagnostic and it also hangs with the version on the display. It seems it is not getting to the I2C bus section? Or do I have the wrong program?

Thanks,
Howard

ARV,

>>Inductors are interesting in Spice simulations.  Usually the amount of resistance in a couple 
feet of AWG-20 is so insignificant as to have any large effect on performance.  I <<

There are several effects one is the DC resistance of the wire which is small. Then the AC
resistance due to skin effect and this varies with frequency and surface area of the wire.
Of course we have inductance as well.

The presence of all of those are what is called Q.  Higher Q is typical of large outer
diameter conductors or even tube, low DC resistance and low intertrun capacitance.

SMT inductors generally fall on the range of 40-70 not great but useful.  Some like
Coilcraft mini and maxi spring are better.  A good inductor using toroid and thick wire
might hit 250 though 200-225 is typical.  

With all that said adding resistor to the perfect devices of LT-spice (or others
like Genesys) is part of trying to make them look real.  Most spice/sim programs
have spaces for user parts when you get to fill in the real part behavior which in
many cases are available from the various vendors.

Capacitors are pretty much the same game save for the ESR is important.
Decent caps MLCC, Mica, ATC, polystyrene, and some ceramics can have
very high Q.  However some ceramics are not and its not important for their
general (bypass, coupling) use but it makes them not very useful for some
types of RF circuits like tuned circuits and filters.

If there is anything to take away is be aware of the parts in use.  Q is only
one factor.  Current handling is a concern at higher power, and self inductance 
and self resonance are as well.  To answer those questions one god to catalogs
and data sheets.  Remembering what was done before that worked also counts.

This might be useful for both Tom and Howard: Every now and then, the serial port on my Mac gets into a funky state, and I can no longer upload to the Nano, and I have to reboot the computer to get it back into a working condition. One time, a partial sketch got uploaded to the Arduino, and I had similar symptoms as Howard: The Version number got displayed, but instead of hanging, the Arduino resetbitself and started over in a loop. Maybe a reboot is in order to get things working again.

As SMD compoents are used the size of the "cheap" chinese pcb´s should be < 100 * 100 mm.

I believe that this forum including Farhan can and shuld be a good potential for an optimized new µBITX!

My previous ideas:

modular design on pcb´s (<100 * 100 mm)

frequency range 10 kHz to 30 MHz

first IF > 45 MHz (to avoid the 2*IF - LO problem) using four pole xtal filters  e.g. 70 MHz (if easily avaliable)? Another "popular IF could be 58 MHz or 58.1125 MHz (used in Hagenuks cordless phones) My be enough NOS filters are laying around.

1) receiver/exciter pcb

2) xtal filter board for the second IF (e.g. 5 MHz) with filters for SSB; AM; FM(?), CW

2) input lowpass filter (corner freq. 1.6 MHz) plus  overlapping bandpass filters (e.g. 1.6 - 4MHz; 4 - 8 MHz, 8 - 16 MHz; 16 - 30 MHz)

3) driver board

5) PA board

6) lpf´s

7) VSWR bridge

8) VFO (several SI5351 ? to avoid crosstalk between outputs of a single SI5351 driven from a single reference (TCXO; or VCXO which could be synchronized to a GPS reference?)

RF signals to be routed via SMA connectors

Of course AGC should be inclueded!

For the mic amp I remember that for maritime ship transmitters there is a requirement to limiting the max RF output via a Mic compressor. Chips like the SSM2167 could easily fulfill such a (similar) spec!

Re: Arduino Hangs

Ihaven't tried this, put something like:

void setup()
{
   int i;

   for (i = 2; i < 14; i++) {
      pinMode(i, OUTPUT);
      digitalWrite(i, HIGH);
      delay(10000UL);
      digitalWrite(i, LOW);
   }
}

You would have about 10 seconds to move your voltmeter from pin-to-pin. You could test the analog pins the same way, as they can also be used as digital pins. The test would at least show that the pins can change state.

Re: Arduino Hangs

Tom, wb6b
 

Is it just that the program hangs, or are you no longer able to upload programs to the Nano?

I've started to have problems uploading programs to clone Nanos with my Mac, after I upgraded to the new Arduino hardware drivers that now include the "Old Boot loader" option in the programmer menu. I even have one Nano where I cannot program the Nano anymore after a failed programming attempt.

However, on my Raspberry Pi, (except for the one was broken in the failed upload) I have no problems uploading programs to Nanos from my collection of cheap clones.

Don't know if this program upload issue-- with the new Arduino system upgrade-- is just limited to my laptop or affects other Mac or Windows users.

I'm going to program a Nano to act as an "ISP" and see if I can program a new boot loader into the currently not working one. Not sure if the cheep Nano clone boot loaders are (or even need to be) tweaked because they use different USB serial chips and possibility different CPU clock frequencies. (Based on the results I was getting with a recent program I wrote, I think some of my cheep clones may be running slower than the expected 16 Mhz, although I have not verified that yet.)

Yes, and the V4 program I was running before loaded properly.

I was hopping I could pick someone's brain before I start to experiment with the code I am running on my Arduino. My Arduino nano died, and I just replaced it with a new one. (I tried to socket it, but the pins didn't plug into any sockets I have.) The code hangs at the version number. Is there anything going on that the code looks for that it is not seeing to move on? I know how to add print statements to see if I can locate where the problem is, but if someone has seen this, maybe you could save me some time.
Thanks,
